Answer:

x = 58, y = 61

Step-by-step explanation:

We can use two properties of a parallelogram to solve this

1. The opposite angles of a parallelogram are equal

2. The sum of the 4 interior angles of a parallelogram equal 360

Using property 1,

Using property 2
(2x - 3) + y + (y + x) + y = 360

3x + 3y + 3 = 360

3x + 3y = 360 - 3 = 357

Divide both sides by 3 to get
x + y = 357/3
x + y = 119  [2]

Add [1] and [2] together to eliminate y and get

x - y + x + y = -3 + 119

2x = 116

x = 116/2 = 58

Use equation [2]

x + y = 119
58 + y = 119

y = 119 - 58

y = 61

Answer:

  6.5

Step-by-step explanation:

You want the definite integral of |2x-3| from -1 to 2 using geometric area formulas.

The attached figure shows the integral to be the sum of the areas of two triangles. The left one has a base of 2.5 and a height of 5; the right one has a base of 0.5 and a height of 1. The areas can be found using the triangle area formula:

  A = 1/2bh

  A = 1/2(2.5)(5) = 6.25 . . . . . area of left triangle

  A = 1/2(0.5)(1) = 0.25 . . . . . area of right triangle

Then the integral is ...

A function that will match the given graph is; f(x) = 2(x - 5)²(x + 2)

In polynomial graphs, we know that the roots are the points where the graph crosses or touches the x-axis.

In this given graph, we see that the graph touches the x-axis at x = 5 and then crosses the x-axis at x = -2. Thus;

The roots of the equation are -2 and 5.

However, when the graph changes sign at a point on the x-axis, it means that point represents double roots. Thus, we will now have three roots which are -2, 5 and 5. The factors of the polynomial are;

(x + 2), (x - 5)²

Now, we see that when x = 0, y = 100 from the graph. Thus;

a(0 + 2)(0 - 5)² = 100

a(50) = 100

a = 100/50

a = 2

Thus, the equation would now be;

f(x) = 2(x - 5)²(x + 2)

The distance of the boat on the right to the finish line is 297.29 m and the distance of the boat on the left to the finish is 294.11 m, so the boat on the left will reach the finish line faster.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The left boat is a little closer to the finish line (100m instead of 110m). On the other hand, the right boat has an advantage, because it is moving more directly toward the finish line (22° instead of 20°).

And, The speed of each boat is 10 m/s.

Now,

Let the hypotenuse = h

So, We can formulate;

For left boat,

⇒ sin 20° = 100 / h

⇒ h = 100 /sin 20°

⇒ h = 100 / 0.34

⇒ h = 294.11 m

For right boat;

⇒ sin 22° = 110 / h

⇒ h = 110 /sin 22°

⇒ h = 110 / 0.37

⇒ h = 297.29 m

Thus, According to the above, the distance of the left boat is less, so it can be inferred that this boat will reach the finish line faster.

Using the slope, the required value of k is 48.

In mathematics, the steeper direction of a line is overall processed by the slope or gradient of the line.

A line's slope can be used to determine how steep it is.

Theoretically, the gradient is calculated as "rise over run" (change in y divided by change in x).

Given is a line that crosses through the origin:

y = mx

Let,s take x = -12 and y = -2.

y = mx

-2 = -12m

m = -2/12

m = -1/6

m is the slope.

The equation now:

y = mx

y = -1/6x

Now, insert:
x = k and y = 8

y = mx

8 = -1/6x

x = 6*8

x = 48

(a) The critical points of the given system of equations are (0,0), (2,2), and (-2,-2).

(b) Near the critical point (0,0), the linear system is: [tex]\frac{dx}{dt} = 2y, \frac{dy}{dt} = -2x[/tex]. Near the critical point (2,2), the linear system is: [tex]\frac{dx}{dt} = -2y, \frac{dy}{dt} = 2x[/tex] Near the critical point (-2,-2), the linear system is: [tex]\frac{dx}{dt} = 2y, \frac{dy}{dt} = -2x[/tex]

(c) The eigenvalues of the linear system near (0,0) are: ±2i. The eigenvalues of the linear system near (2,2) are: ±2i. The eigenvalues of the linear system near (-2,-2) are: ±2i. These eigenvalues indicate that the nonlinear system is stable near each of the critical points.

(d) The phase portrait of the nonlinear system will be a series of circles centered at each of the critical points and will show that the system is stable near each of the critical points.

A critical point of a system of equations is a point at which the derivative of the system is equal to zero.

To find the critical points of the given system, we can set the derivative of each equation equal to zero and solve for x and y. For the first equation, this gives us:

[tex]\frac{dx}{dt}[/tex] = (2 + x)(y - x) = 0

If we set the derivative equal to zero, then either (2 + x) = 0 or (y - x) = 0. If (2 + x) = 0, then x = -2. If (y - x) = 0, then y = x.

For the second equation, setting the derivative equal to zero gives us:

dy/dt = (4 - x)(y + x) = 0

If we set the derivative equal to zero, then either (4 - x) = 0 or (y + x) = 0. If (4 - x) = 0, then x = 4. If (y + x) = 0, then y = -x.

Therefore, the critical points of the given system are (-2,0), (4,0), and (0,0).

Next, we can find the corresponding linear system near each critical point by finding the Jacobian matrix of the given system at each critical point. The Jacobian matrix is a matrix of the partial derivatives of the system with respect to x and y.

At the critical point (-2,0), the Jacobian matrix is:

[(2 + x)(y - x) (2 + x)(y - x)]

[(4 - x)(y + x) (4 - x)(y + x)]

Evaluating this matrix at the point (-2,0) gives us:

[(-2)(0 - (-2)) (-2)(0 - (-2))]

[(-2)(0 + (-2)) (-2)(0 + (-2))]

= [4 4]

[-4 -4]

At the critical point (4,0), the Jacobian matrix is:

[(2 + x)(y - x) (2 + x)(y - x)]

[(4 - x)(y + x) (4 - x)(y + x)]

Evaluating this matrix at the point (4,0) gives us:

[(4)(0 - 4) (4)(0 - 4)]

[(4 - 4)(0 + 4) (4 - 4)(0 + 4)]

= [-8 -8]

[0 0]

At the critical point (0,0), the Jacobian matrix is:

[(2 + x)(y - x) (2 + x)(y - x)]

[(4 - x)(y + x) (4 - x)(y + x)]

Evaluating this matrix at the point (0,0) gives us:

[(2)(0 - 0) (2)(0 - 0)]

[(4 - 0)(0 + 0) (4 - 0)(0 + 0)]

Answer:

  a. 31 months

  b. $818.32

  c. $168.32 interest

Step-by-step explanation:

Given that Joe makes a minimum payment of $21.45 on his credit card purchase of $650 with an APR of 19.85%, you want to know ...

If the balance is reduced by $21.45 per month, it will take ...

  $650/($21.45/mo) ≈ 30.3 months

to pay off the balance.

Joe will be making payments for 31 months.

The total amount Joe pays for his sound system is the sum of its initial cost and the total of interest payments. That sum is ...

  cost + interest = total paid

  $650 +168.32 = $818.32

Joe will pay a total of $818.32.

The total amount of interest Joe pays is $168.32.

__

Additional comment

If the total payment each month is $21.45, then it will take 43 months to pay off the system, for a total cost of $909.61, of which $259.61 is the cost of the credit. (The finance charge is paid first from this payment amount, so the amount that goes to reduce the balance is less.)

The average grade received on two tests and the final exam is 78.67%

What is average?

The ratio of the sum of the values in a particular set to all the values in the set is the mean value, which is the definition of the average.

The average formula has numerous practical uses. If we were asked to determine the average male height in India or the average age of the men and women in a group, we would add up all the data and divide it by the total number of data points.

Given, the grades in tests are 74% and 82%. Also, the grade on final exam is 80%.

Now, considering that we have to find the average grade in tests and final exams combined, we put the average formula.

Average grade = Sum of percentages of each exam/Total exams

Thus, average is

= 236%/3

The correct option that describes the vertical asymptote is; B: There is a vertical asymptote at x = 4 because Limit of g (x) as x approaches 4 minus = infinity and limit of g (x) as x approaches 4 plus = infinity

A vertical asymptote of a graph is defined as a vertical line x = a where the graph tends toward positive or negative infinity as the inputs approach a.

A vertical asymptote is a value of x for which the function is not defined, that is, it is a point which is outside the domain of a function;

In a graph, these vertical asymptotes are given by dashed vertical lines.

An example is a value of x for which the denominator of the function is 0, and the function approaches infinity for these values of x.

We are given the function;

g(x) = 2(x + 4)²/(x² - 16)

Simplifying the denominator gives;

(x² - 16) = (x + 4)(x - 4)

Thus, our function is;

g(x) = 2(x + 4)²/[(x + 4)(x - 4)]

(x + 4 ) will cancel out to give;
